EPIGRAPHY (Gr. ἐπί, on, and γράφειν, to write), a term used to denote (1) the study of inscriptions collectively, and (2) the science connected with the classification and explanation of inscriptions. It is sometimes employed, too, in a more contracted sense, to denote the palaeography, in inscriptions. Generally, it is that part of archaeology which has to do with inscriptions engraved on stone, metal or other permanent material (not, however, coins, which come under the heading Numismatics).
